We have a 20 gal. electric water heater in our 4104. I don't think we need to carry so much water that we really can't use so I would like to replace it with something smaller or even a tankless heater. What size water heaters are you using in your bus? Any tankless heaters?

2.5 ga under counter wet bar type found at lowes. Going on 6 years now and never let us down. Its quicker to heat a little water than it is if you have 20 gal and use part, then you cool your hot water with what you replace. My thoughts anyway!Ace

We had a Poloma instant hot water heater in the last bus. I liked it a lot. We have a 10 gallon electric one now. It's okay, but if I ever have to due something with it, we will go tankless. Of course, you could say that this gives me 10% more fresh water capacity.

Luvrbus we promote cold showers down here! Trying to cut back on the population if you know what I mean!Like I said, the small water heater does fine for the two of us. Its good for dish washing too. We have a W/D but not hooked up yet so not sure about that but one thing it DOES do and that is recoup very fast!Ace

I have my 130gal water tank and 2-10 gal electric water heaters from Home Depot under my bed. One water heater feeds into the next with the final water heater wired through the inverter so I have hot water all day long while driving. I keep the temp down on the water heaters to prevent build up hence NO maintenance in the 13 years I've been using them. They take about 45 minutes to heat from cold. It is the simplest water heating method- no propane, no coolant hoses going to it, no Diesel fuel fired heaters, no circulation pumps, just silent hot water. I like it so much, I'm going to use this system again with my next conversion. Good Luck, TomC

We have one 10 gallon electric water heater from Home Depot. We reset the thermostat to the hottest setting. Turn it on for 45 minutes and we have 10 gallon of 150 degree water. Doesn't take much of this added to cold water for a shower. We usually turn water heater on while preparing supper. Plenty of hot water to wash dishers, 2 showers and still have hot water left next morning. If you can reset the thermostat on the 4 gallon iniot it may work becaue you would use less of the hot and more cold to acheive the same water temperature. Jack
